RPOP Ring Control
When set high, the block BIP-8 output bit (BLKBIPO) indicates that path BIP-8 errors are
to be reported on a block basis to the transmit path overhead processor (TPOP) block. A
single path BIP error is reported to the return transmit path overhead processor if any of the
path BIP-8 results indicates a mismatchWhen BLKBIP is set low, BIP-8 errors are reported
on a bit basis.
When set high, the block BIP-8 bit (BLKBIP) indicates that path BIP-8 errors are to be
accumulated on a block basis. A single BIP error is accumulated if any of the BIP-8 results
indicates a mismatch. When BLKBIP is set low, BIP-8 errors are accumulated on a bit
basis.
The enable size bit (ENSS) controls whether the SS bits in the payload pointer are used to
determine offset changes in the pointer interpreter state machine. When a logic one is
written to this bit, an incorrect SS bit pattern (i.e., not equal to 10) will prevent RPOP from
issuing NDF_enable, inc_ind, new_point and dec_ind indications. When a logic zero is
written to this bit, the received SS bits do not affect active offset change events.
The stuff opportunity spacing control bit (SOS) controls the spacing between consecutive
pointer justification events on the receive stream. When a logic one is written to this bit, the
definition of inc_ind and dec_ind indications includes the requirement that active offset
changes have occurred a least three frame ago. When a logic zero is written to this bit,
pointer justification indications in the receive stream are followed without regard to the
proximity of previous active offset changes.
